In Triton Tech Of Texas, LLC v. Nintendo Of America, Inc.[1] the Federal Circuit affirmed a ruling by the United States District Court for the Western District of Washington that Triton’s U.S. Patent No. 5,181,181 (“’181 Patent”) was invalid for indefiniteness. The case revolved around the claims of the ‘181 Patent and the use of a Wii RemoteTM with a computer. The patent had claims reciting an input device that provided information to the computer about cursor movement much like a conventional mouse, except that the information provided by the ‘181 device was related to movement in three dimensions. The claimed input device included acceleration sensors, rotational rate sensors, an analog-to digital converter, buffer memory, and an “integrator means associated with said input device for integrating said acceleration signals over time to produce velocity signals for linear translation along each of … first, second and third axes.”[2]
